Now referring to FIGS. 2, 3 and 5, 1 denotes the main shaft of themachine, a cam shaft 2 rotatably mounted in the machine frame 27 abovethe former shaft and in a parallel relation thereto. The shaft 2 isdriven through a reduction gearing, comprising Wheels 37, 38, 40 and 41,from the main shaft 1, and provided with a cam block 3 rotatable withthe shaft 2, as will be hereinafter described. Two groups of pushbuttons 4a and 4b, the number of which corresponds to that of cams ofsaid packet 3, said 3,279,402 Patented Oct. 18, 1966 button groups beingarranged in two stages adjacent to each other in the machine frame 27.Each of the buttons 4 of the upper group 4a is formed with an arm 5,while each button 4 belonging to the lower group 4b is provided equallywith an arm 6, said buttons of both groups 4a and 4b are each providedwith boss 7 and flange 8 formed integrally therewith, said flanges ofthe both groups being mounted alternatively on a supporting shaft 9, asshown in FIGS. 3 and 5, which shaft is stationarily arranged in parallelrelation to shafts 1 and 2. Each of buttons 4 and 4' is part of aselector member including a depending leg 10 as well as an upperprojection 11 having an opening 11a, into which is inserted a pin 12,upon the latter an engaging pawl 13 is pivotally mounted. The pawl 13 isprovided with upper and lower engaging projections 13a and 13b. On theother hand, the flange 8 is fitted with a spring 14, the upper end ofwhich bears against an angle bar 16 fixed by means of set screws 15 onto the machine frame 27, while the opposite lower end urges the leg 10of the corresponding push button 4 or 4' outwardly. A further pushbutton 17 arranged at the left hand end of push button groups 4a and 4b,serves for returning already pushed-in button or buttons, if any, to theinitial inoperative position, as will be hereinafter described more indetail, thus being provided with none of said engaging pawls. When anyof the push buttons 4 and 4' is pushed-in into its operative position,the engaging projection 13a of the corresponding pawl 13 is brought intopressure-engagement with the corresponding cam of packet 3, so that withrotation thereof said pawl 13 reciprocates in rocking motion about pin12. The motion is transmitted through a transmission plate 18, which isat its one end pivotally mounted on a supporting shaft 19, the latterbeing fixed to the machine frame 27, while the opposite end of saidplate is fixed by means of set screws 21 to a further supporting shaft20, the latter shaft being pivotally mounted in the machine frame. Theupper engaging projection 13b of pawl 13 is kept in pressure-engagementwith the co-operating surface 18a of said plate 18 and an arm 22 isfixed on one end of said further shaft 20, which is, as above referredto, fixedwith motion-transmitting member 18, so that said rocking motionmay be transmitted through arm 22 to the needle-bar assembly of themachine.

On the upper end of a needle-bar support 61, a pivot pin 6 is mountedand turnably supports the flanges 62a and 62b of an operating rod 62 towhich an operating member 63 is secured by screws 64. As shown in FIGS.2 and 9, an edge 63a of member 63 is in contact with arm 22 of themotion transmitting means 18, 20, 22. Consequently, the reciprocatingrocking motion of arm 22 is transmitted to the needle-bar assembly. Aspring 65 is mounted on the needle-bar support 61 and engages themachine frame at one end to :bias the needle-bar support into a normalposition so that member 63 is biased to engage arm 22.

In the drawings, 23 represents a rockable elongated locking meansarranged in parallel relation to cam shaft 2, said locking means havingthe form of a bar pivotally mounted at its both ends by means of pins 24and 25, respectively. A spring 26 is mounted on said pin 25, one end 260of the spring bears against said stopper 23 and the opposite end 26bengages with the machine frame under pressure, thus the spring, as willbe hereinafter explained more fully, serves for returning the bar 23 toits initial position. This locking bar 23 is provided with alongitudinal groove 23, and a projection 10" on the tip of leg 10 of anyof the push buttons 4 and 4 is arranged to engage groove 23 while theelongated projection 23a engages the recess 10' on the tip of therespective leg 10. A separate stop means 28 of L-shaped cross-section isarranged in parallel relation to the aforementioned locking bar 23within the machine frame. When push buttons 4 and 4' are returned totheir off-service positions, the end surface 10" of each leg 1f isbrought into engagement with the stopper plate 27 and thereafter reststhereon.

In operation of the above mentioned mechanism, the operator selects adesired zigzag sewing pattern m denoted on a push button 4 or 4 andpushes it in its service position, the button under consideration isrotated forwardly about the shaft 9 against the action of spring 14fixed to the flange 8, thereby the projecting leg 10 is rotated in theforward direction at the same time. As already explained, the projection11 is provided with pin 12 fixed thereto and the pawl 13 is adapted topivot about the pin, the engaging projection 13a of each pawl 13 beingurged to engage with the co-operating cam surface belonging to thepacket 3, while the projection 10 on the leg 16 of the respective pushbutton 4 or 4 engages with the longitudinal groove 23 on the rockablelocking bar 23, so that unintentional return of the button in its normaloff-service position is positively prevented. In this case, the engagingprojection 1311 under consideration is kept in engaging contact with thecorresponding cam surface, so that with rotation of the cam packet thechange of the cam lift causes the co-operating pawl 13 to rock about thepin 12 to and fro, the movement of the pawl is thus transmitted to themotion-transmitting member 18 to cause it again in rocking motion, asthe opposite engaging projection 13b of the pawl is kept in pressureengagement with the co-operating surface of the plate 18 (see FIG. 3),which is as was already explained pivotally mounted, thus theneedle-assembly (see FIG. 9) operatively connected by linkage 62, 63 andarm 22 (see FIG. 2) with said plate 18 is operated to carry out thedesired lateral rocking motion known per se.

When it is desired to change the already selected stitch pattern to anyother suitable one, the operator pushes-in the correspondingly, newlyselected push button, thereby, just in the same way as referred toabove, the related pawl 13 is brought into engagement with both cam andtransmission plate. In this case, however, the operating projection orleg 10 during the advancement of the push button pressed with itsangular edge 10a upon the inclined surface 23 formed on locking bar 23,which is thereby caused to turn downwards. Further, when the edge 10apasses over the top ridge 23a of the surface 23" and projection 10engages in the groove 23, any other leg 10, which has been alreadyengaged therein, is disengaged from the locking bar 23, thus causing thealready selected and pushed-in button to return to the normal offserviceposition. In this returning, the newly off-serviced push button is keptin position by engagement of its leg 10 with the L-shaped stop bar 29.After cam selection has been thus altered, a new stitch patterncorresponding to the newly selected-out push button and illustratedthereon as is clear from FIG. will be produced with continued running ofthe machine, until a still other cam selection will be carried intoeffect at the operative will.

According to this invention, any combination of two or more stitchpatterns is obtainable, by pressing-in two or more desired push buttonsat the same time, thereby causing the latter simultaneously to engageboth the corresponding cams and the transmission plate While theactuated push buttons are held in operative positions by projection 23aengaging in the respective recesses When any desired stitch pattern hasbeen produced and come to the end, the related pawl 13 of the pushed-inbutton is kept in the engaged position. Disengagement and return of thepawl is carried out by pressing-in a separate push button 17 mounted atthe left hand adjacent position, as clearly seen from FIGS. 2 and 5.This push button 17 is provided with no pawl or latch such as 13, as wasalready explained, and serves, when depressed, to disengage and returnone or more already engaged normal push buttons. Clearing button 17 hasa projecting edge 17a which engages the inclined surface 23" when button17 is operated. When edge 17a passes over edge 4 23a, the projection 10"of any depressed cam selector button 4, 4' is released.

As will be explained hereinafter referring to FIGS. 6- 8, the cam packet3 is exchangeable with any other suitable set. When exchanged in thisway, operation of one and the same push button will naturally produce adifferent stitch pattern. For this purpose, although not shown,diagrammatic representations in on each normal push button 4 or 4 may bepreferably arranged in two or more suitable stages, or distinguishedfrom each other stitch group by different colors.

The present machine can be further improved by employing a novel camblock mounting arrangement, which will be explained below by way ofexample referring to FIGS. 68. The cam shaft 2 is provided at its oneend with a central bore 2a, into which is inserted a pin 2% of an axlemeans 29 which is provided with a flange 2% formed thereon and a spring39, which is loosely mounted on the stern thereof, thus united axlemeans is rotatably mounted in a hearing or bore 31 of supporting part 32provided in the machine frame 27. The cam 3a occupying one of the endpositions, say, the left hand position in FIGS. 2 and 6, of the camblock 3 is fixed on tubular shaft 2, as shown in FIG. 8, while theopposite end cam 3b is arranged to be detach-ably mounted on the shaft 2by means of key 33 and groove 34 (FIGS. 6 and 8). Be tween said bothextreme cams 3a and 35, there are arranged a plurality of intermediatecams 3c in direct contact relation one after another to constitute thecam block 3 together with the end cams. The cam block 3 is provided witha hole 35 passing in effect through all of the constituent cams 3a, 3band 30. When assembled, a pin 36 is inserted into the hole 35 to formrigidly a cam block in effect by a number of the cams. A driving gear 37is fixed on main shaft 1 and meshes with a driven gear 38 fixed on anintermediate vertical shaft 39 at its one end, while a driving wheel 40fixed on the opposite end of the said intermediate shaft engages with adriven toothed wheel 41 rotatably mounted on a shaft 42, said lattershaft 42 being fixedly mounted in the machine frame 27. The toothedwheel 41, as shown in FIG. 8, is provided with a pair of couplingprojections 41c projecting the end surface 41]) on the boss 41a thereof,the said projections being adapted to engage the mating lateral grooves31; cut in the end cam 3a integral with cam shaft 2 for the purpose oftransmitting the driving force from the main shaft 1 for rotation of camblock 3. A stepped connecting pin 44 is adapted to be inserted with itsstem 44a in a bore 21') cut in the left hand end of cam shaft 2, as isclearly illustrated in FIG. 8, while the enlarged cylindrical portion44b is so dimensioned that it detachably fits in the central bore 41d oftoothed wheel 41, thus said pin, when assembled, serves for supportingleft hand end of cam shaft 2, while the right hand end of the latter isrotatably mounted through axle means 29, after assembled, in the bearing31, thereby the coil spring 30 urging the shaft 2 leftwards in FIGS. 2,5, 6 and 8 through the intermediary of projecting flange 29b and thuspositioning the cam block 3 at its normal service position. An L-shapedmanipulating lever 45 is provided at its one end with an operating knob45a, and at the opposite with a fork 45b, which engages the head 46a ofa screw 46 screwed into the right hand end of connecting pin 29, thesaid lever 45 being pivoted at its intermediate portion on a pivot pin47, the latter being fixed to the machine frame 27 by means of a setscrew 48.

When it is desired to dismount quickly the cam block 3 from the machine,the operator presses down the opcrating knob 45a, thereby causing theforked end 45b of bellcrank lever 45 to turn in the counter-clockwisedirection and thus shifting stop 46 together with axle means 29 and pin29a against the action of spring 30 in the axial direction, until thepin 29a is disengaged from the bore 2a at the right hand end of tubularsupport 2. Thus, the operator can easily dismount the assembled camblock 3 together with tubular support shaft 2 from the machine.

Although the invention has been described in considerable detail in theforegoing for the purpose of illustration, it is to be understood thatsuch detail is solely for this purpose and that variations can be madetherein by those skilled in the art without departing from the spiritand scope of the invention except as set forth in the claims.
